Abstract

We consider equations of hydrodynamics with certain additional constraints. Group-theoretical methods are applied to find invariant solutions of a system of Euler equations that satisfy the Rankine–Hugoniot conditions.
KeywordsEuler equations, group-theoretical methods, invariant solutions
